The third member of the cumulene-thione series H2CnS, propadienethione, has been produced by pyrolysis of cyclopenteno-1,2,3-thiadiazole and detected by microwave spectroscopy.The rotational constants from a number of isotopomers have been used to derive a molecular geometry, which shows that propadienethione is a planar molecule of C2v symmetry, unlike propadienone which is kinked.A fully optimized geometry from a set of ab initio calculations done at the MP3/6-31G level is in agreement with the experimental results.The dipole moment has been calculated from the Stark effect to be 2.064 Debye.

The third member of the cumulenethione series, H2CnS, propadienethione, has been produced by pyrolysis of cyclopenteno-1,2,3-thiadiazole and detected by microwave spectroscopy which provided rotational parameters for the 32S and 34S isotopomers, the dipole moment , and an indication that propadienethione is a planar molecule of C2v symmetry.
A NOVEL ROUTE TO THIOKETENES BY FLASH VACUUM THERMOLYSIS OF SILYLATED KETENE DITHIOACETALS, SYNTHESIS OF PROPADIENETHIONE.

Flash vacuum thermolysis (fvt) of silylated ketene dithioacetals 2 leads to reactive thioketenes 1.This method, added to a retrodienic reaction, allowed access to propadienethione 3.
